Abstract
A rectangular microstrip patch antenna is proposed in this paper. The proposed antenna is composed of a rectangular patch with a ground plane having compact profile, simple structure and easy for fabrication. The rectangular patch antenna is slotted with two type of rectangular and semi-circle slots so as to ensure a broad bandwidth. The antenna is constructed using a FR4 substrate with relative permittivity εr =4.4. The simulated results reveal that antenna shows impedance bandwidth 3.10 GHz-10.06 GHz and the VSWR< 2 through the impedance bandwidth and the return loss at that point is -10db. Different parameters like operating frequency, VSWR, radiation pattern, 3D polar plots are simulated using HFSS Software. The antenna can be used for ultra-wide band application. Finally, the proposed design has wide applications in the field of communication like Bluetooth operations, Wi-Fi, Wi-MAX, Telemedicine and UWB applications.
